Heat Apparatus Dealers in Madh, Mumbai

The apparatus consists of a small test sphere. This sphere is heated by a hot bath, till the steady state is reached and then it is coolled in air or water / oil. During both, heating and cooling of sphere, temperature of sphere is a function of time and hence, it is a unsteady state of heat transfer process. The temperature of sphere is measured by thermocouple. The hot bath is provided to heat sphere with temperature controller to facilitate to conduct experiment at different temperatures. Specifications Test piece with thermocouples - 2 No.s of different materials. Hot bath with heater and controller. Cold bath. Digital Temperature Indicator.   Service Required Floor Space - 1.5 m X 1.5 m 15 Amp., 230 V.A.C. power supply.

The HDT/VSP instrument is used for determining the deflection temperature limit for specific application and comparing the heat softening characteristics of thermoplastic material at a constant load in oil upto 300 Deg. Co.cPlastic materials being heat sensitive in nature has a lot of bearing on its thermal environment for it's performance. Though their behaviour in thermal conditions is very complex some simple yeild tests are used to predict it's behaviour and performance in a given condition. "VICAT SOFTENING POINT" or "HEAT DISTORTION TEMPERATURE" is one of such yeild points very commonly employed with such demanding applications. Vicat test consist of penetrating a unit size indentor in a plastic surface with predefind load under constant rate of environmental temperaturerise. Heat distorsion test, as it is sometimes called, consistes of deflecting a simply supported beam of test material under similar heating conditions & with a predefined stress application.HDTTest for deflection temperature of plastics under flexural load. Heat distoration temp. is the temp. At which a sample deflacts by 0.1 inch. (2.5 mm). Standart test methods: ASTM D648, BS 2782 method 102, ISO R75.VSTVicat softening point is the temperature at which the needle penetrates 1 mm into the sample. Standard test methods : ASTM D1525, BS 2782 method 102D, ISO R306.
